Political variations in pandemic lifestyles and COVID-19 vaccination by age cohort in the United States.

While recent scholarship suggests that political affiliation is a robust predictor of pandemic behaviors and COVID-19 vaccination status, research has yet to examine whether the impact of political affiliation on these outcomes vary by age. Drawing on health lifestyles theory, we contribute to the social epidemiology of infectious disease behaviors by testing whether the impact of political affiliation on risky pandemic health lifestyles and COVID vaccination varies by age cohort. We employ data collected from the 2021 Crime, Health, and Politics Survey (CHAPS), a national study of adults from the United States, to formally assess this understudied association. In all models, Democrats reported less risky pandemic lifestyles compared to their Republican counterparts. Moreover, Democrats displayed greater odds of being vaccinated than Republicans or Independents. Further, the impact of political affiliation on vaccination status varied by age cohort, such that the impact of political affiliation was stronger among the oldest adults in our sample. Our analyses contribute to the growing study of politics and health lifestyles by challenging theoretical perspectives and cultural narratives that claim that older adults are less swayed by political influence when it comes to healthcare decisions. Our results help better our understanding of the ways in which political discourse shapes adopting public health recommendations.
